Claims

[Scope of utility model registration request]

(1) Both side walls 3°3 expanding downward on the bottom side of the horizontal plate 2
A reinforcing rib 5.5 having a triangular cross section and consisting of a bottom surface 4 and a bottom surface 4.
The required number of ribs are arranged in parallel and bent, and at the apex of the triangular reinforcing rib 5, the apex portions of the both side walls 3.3 are brought into contact with each other to form a closed apex portion 13. In the formed form 1, both ends of the form 1 are crushed by a press machine from both the surface of the horizontal plate 2 and the bottom surface of the reinforcing rib 5, and a hook part of the required width is formed in the middle part of both sides. 7, and a portion 1 in which the end of the reinforcing rib 5 is crushed near the hooking portion 7
A notch 15 with a required width H and a required length is bored in the intermediate flat part 14 between 6 and 16, so that the concrete in the upper and lower parts of the formwork 1 is A formwork for a concrete floor slab characterized by forming a continuous concrete floor.

(2) Utility Model Registration Scope of Claims In the formwork for concrete deck slabs according to claim 1, pressing is performed from both sides of the surface of the horizontal plate 2 and the bottom surface 4 of the reinforcing ribs 5 in the middle part of the formwork 1. A concave part 10 for the same purpose as the above-mentioned latching part 7 is formed in the intermediate part of both surfaces by crushing with a machine, and in the vicinity of the concave part 10, a part between the reinforcing ribs 5 and 5 is formed. A cutout window 15' with a required width H' and a required length L' is bored in the flat part 14', and when constructing a concrete floor, the concrete in the upper part of the formwork 1 and the concrete in the lower part are continuous with each other. A formwork for a concrete floor slab characterized by being adapted to form a concrete floor.
